Learn what causes circular motion. The dynamics of circular motion.

## Centripetal Acceleration

In the following interactive, you can adjust the radii and angular velocities of two different objects and observe their changes in centripetal acceleration according to the relationship $a = r\omega^2$.

See if you could obtain the same magnitude of acceleration with different values of $r$ and $\omega$.
